(40 points plus ) hi i'm having some trouble with this math question and i'm really trying to do well to pass math this year.)

(question)
match each interval with its corresponding average rate of change for the graph shown below.

1.
0 ≤ x ≤ 1

2.
-2 ≤ x ≤ -1

3.
-2 ≤ x ≤ 0

4.
1 ≤ x ≤ 2

5.
-1 ≤ x ≤ 0

6.
0 ≤ x ≤ 2

*these are the answers that need to be matched
-0.5

-1

-0.375

-1.5

-0.25

-2

(* you)

Step-by-step explanation:

1.  cannot be answered because there isn't a positive number

2. -1.5, -1, -2

3.  -2, -1.5, -1

4.again can not be answered because there are not any positive numbers

5.  -1, -5, -0.375, -0.25

6. again can not be answered because there aren't any positive numbers

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

1. supplementary angles

2. acd and bcd
